🌸 Quick answer
What does fractional CO2 laser treat? Fractional CO2 laser uses carbon-dioxide energy to create microscopic columns of controlled heat in the skin. This removes damaged tissue and triggers strong collagen remodelling, which smooths acne scars, deep lines, enlarged pores and rough texture. It is one of the most effective resurfacing options and needs fewer sessions than gentler lasers, though downtime is longer. Results continue improving for 3–6 months after each session.
What is fractional CO2 laser?
Fractional CO2 laser is an ablative resurfacing treatment that creates micro-channels in the skin, removing damaged tissue while leaving surrounding areas intact for faster healing. The controlled heat drives collagen remodelling, so it is one of the most trusted options in Seoul for acne scars, deep lines and overall rejuvenation.
Protocols are customised from mild to deep depending on your skin and concern, and it is often combined with subcision, boosters or RF microneedling for scarring. If you need less downtime, gentler erbium resurfacing may be an alternative.

Fractional CO2 Laser FAQ
How many fractional CO2 sessions will I need?
Mild texture issues may need one session, acne scars 2–3 and deep scars or wrinkles 3–5, spaced 6–12 weeks apart. Results keep improving for 3–6 months after each.
Does fractional CO2 laser hurt?
Numbing cream is applied first, and most people feel warmth or stinging during the short passes. Deeper settings feel stronger but are brief.
How much downtime is there?
Light CO2 means a few days of redness and flaking, while deep CO2 can mean 7–14 days of redness and crusting, with pink skin for several weeks.
Is fractional CO2 safe for darker skin tones?
It needs caution. Devices and settings are chosen for melanin-rich skin, but very dark or tanned skin carries a higher risk of pigment change, so your doctor assesses carefully.
How is CO2 different from erbium resurfacing?
CO2 delivers stronger, deeper resurfacing with more downtime, while erbium spreads less heat for faster healing and a lower risk of pigment change on suitable skin.
Can CO2 laser be combined for acne scars?
Yes. For deeper scarring it is often paired with subcision, boosters or RF microneedling within a tailored acne-scar plan.
